If you read history you can see that many things are used as barter in hard times.
In Mary Chesnut’s Civil War diary, even though the well to do were buying gold, yarn was being used for barter in NC. (She had fled Columbia, SC ahead of Sherman’s burning raids.)
After WWII, in Germany as displaced persons were trying to get by and avoid being turned over to the Russians, cigarettes became the currency amongst many of them.
I’ve learned it is all about what you have and what you need, or what is needed locally and what you can trade.
We just don’t know what it will be. Is it cold where you live, will folks be unable to heat their homes, maybe blankets and warm clothes will be bartered? Do you live in the city where there is trouble with gangs, maybe ammo will be bartered?
Be prepared to take care of yourself and have something extra.

We're all going to have to deal with drug addicts that can't get a fix - it's gonna be scary.
